Bonjour à tous,
J'ai un HP Pavilion 15" ab250nf, avec Windows 10 de base, sur lequel j'ai installé
Ubuntu 16.04 en dual-boot via live-usb. Tout s'est bien passé, j'arrive sur Ubuntu, mais
pas d'internet.
Quelques jours après, màj Windows 10, et
plus de GRUB au démarrage.
Avec Echap au démarrage pour accéder au BIOS, je peux accéder à mon Ubuntu sans problème. Juste un peu contraignant, j'aimerais remettre Grub. Seulement une fois dans Ubuntu, j'ai besoin d'internet pour télécharger boot-repair.. donc impossible de réparer mon grub.
Vient donc le 2ème et principal problème: comment configurer mon wi-fi ?
(Pour Grub, rien de vital pour l'instant, je pense que je pourrais le réparer sans problème dès lors que mon wi-fi marchera.)
Je regarde donc la doc ubuntu sur le wi-fi, je configure avec network manager. Je précise qu'il détecte bien le wi-fi, j'avais même réussi à ce qu'il s'y connecte la première fois que j'étais arrivé sur Ubuntu, mais pas d'internet. Le wi-fi parait bon, mais rien quand je lance Firefox.
Ma carte graphique est une Realtek RTL8723BE, elle parait avoir déjà posé plusieurs soucis de wi-fi..
Voici quelques infos sur ma config :
